CT Texture Analysis Effect of Neoadjuvant Stereotactic Body Radiation Therapy (SBRT) in Borderline Resectable and Locally Advanced Pancreatic Cancer

To evaluate changes in texture analysis parameters of CT images after neoadjuvant stereotactic body radiation therapy (SBRT) in patients with borderline resectable and locally advanced pancreatic adenocarcinoma. Pre- and post-SBRT contrast-enhanced CT examinations of 49 patients were retrospectively evaluated. 3D regions of interest were manually drawn on arterial- and portal-phase CT images to comprise the whole tumor. Tumor volume and 47...
